Description

[Detailed description of the invention] This invention relates to a support installation device for sheet waterproofing construction surfaces, and more specifically, a device for installing support supports such as fences and ramps on the floors of elanders, rooftops, etc. on which waterproof sheets made of soft vinyl chloride are laid. .

In the case of this type of column mounting device, the column must be erected and fixed on a floor surface on which a waterproof sheet made of soft vinyl chloride or the like is laid, so the bolts and screws for fixing it are It will penetrate the sheet, so sufficient consideration must be given to waterproofing this part.

However, conventionally, as shown in FIG. 3, this type of column mounting device has been constructed by laying a waterproof sheet 24 made of soft vinyl chloride or the like on a subfloor 20 of a building frame made of concrete or the like. On the seat, attach the mounting plate 22 welded and fixed to the lower end of the support column 21 in the form of a flange, using the fixing screws 26.
The waterproof sheet 24 is penetrated by the subfloor 2 of the building frame.
0, and then the periphery of the mounting plate 22 and the periphery of the head of the fixing screw 26 were sealed with a sealant 23. However, not only are water leaks likely to occur due to improper installation of the sealing material 23, but also the sealing material itself deteriorates and is damaged over time, making it impossible to maintain a complete waterproof effect over a long period of time. There were problems such as poor durability.

This invention is intended to solve the above-mentioned problems, and hereinafter, an embodiment whose configuration is shown in FIGS. 1 and 2 will be described.

In these figures, reference numeral 1 denotes a support such as a fence or a ramp constructed on a balcony or rooftop, and a suitable screw-fastening piece 8 is inserted and fixed at the lower end. Reference numeral 2 designates a mounting board in the form of a disc or the like, which is made of a so-called PVC steel plate or the like, in which resin coating layers 2b and 2c made of vinyl chloride resin or the like are adhesively fixed to the upper and lower surfaces of a metal core plate 2a made of a steel plate. Therefore, the mounting board 2
is the mounting screw 3 inserted through the screw hole 7 from the bottom side.
is integrally fixed to the lower end of the column 1 in the form of a flange by screwing into the screw piece 8. On the other hand, the mounting board 2 itself is placed on a waterproof sheet 4 made of soft vinyl chloride laid on a floor base 5 of a concrete frame, and is firmly attached to the floor surface with fixing screws 6 passing through the sheet. At the same time as being fixed, the resin coating layer 2c on the lower surface side is welded and integrated with the upper surface of the waterproof sheet 4 in a watertight manner using a solvent-based adhesive at a position inside the fixed portion by the fixing screws 6. . 12 indicates this annular weld. However, the welded portion 12 may be formed substantially entirely on the lower surface of the mounting board 2. Note that the fixing screw 6 is attached to the mounting board 2.
It is firmly screwed and fixed to the floor base 5 by screwing into the split-leg type anchor plug 11 that has been buried in the floor base 5 in advance through a mounting hole 13 drilled in the floor base 5.

Reference numeral 10 denotes a waterproof cover made of synthetic resin, preferably made of a soft vinyl chloride sheet, etc., and is placed over the top surface of the mounting board 2 with the support 1 passing through the support through-hole 9 protruding from the center. , and the periphery of the support through-hole 9 is watertightly welded and integrated with the resin coating layer 2b on the upper surface side of the mounting board 2 around the support 1 by an annular weld 14 using a solvent-based adhesive as described above. . Furthermore, this waterproof cover 10 has a skirt part 10a extending outwardly from the mounting board 2 at the peripheral edge, and the skirt part 10a extends outwardly from the mounting board 2.
covers the peripheral side surface of the mounting board 2, and the lower surface of the peripheral edge is integrally welded and joined to the waterproof sheet 4 in a watertight manner with a welded portion 15 made of the same solvent-based adhesive as described above.

In order to construct the mounting structure for the support column 1 as described above, as shown in FIG.
are integrally bonded to the mounting board 2 at the welding part 14, and after attaching the support column 1 to the mounting board 2 with the mounting screws 3, the mounting board 2 is attached to the waterproof sheet using the adhesive part 12 and the fixing screws 6. 4. Fix it on top. At this time, screw the fixing screw 6 into the waterproof cover 1.
By bending the hakama part 10a of 0 upward,
This can be done by exposing the mounting hole 13.
Next, the hakama part 10a at the periphery of the waterproof cover 10 is folded in along the circumferential side of the mounting board 2, and the lower surface of the periphery is welded and joined to the waterproof sheet 4 by a welded part 15 made by applying a solvent-based adhesive. The installation of the support column 1 is completed in the manner shown in Figure 1.

Note that the synthetic resin waterproof cover 10 is
It is also possible to use one shaped in the cross-sectional shape shown in the figure. In this case, the material may be made of hard synthetic resin. In this case, it goes without saying that after the mounting board 2 is fixed on the floor surface, the waterproof cover 10 is welded to the board.

Since the strut mounting device according to this invention has the above-mentioned structure, the strut 1 is fixed on the sheet waterproofing surface via the mounting board 2 which is integrally fixed to the lower end of the strut 1. Not only can the screw 6 be used to make the work sufficiently strong with a relatively simple work, but also the waterproof effect of the mounting part can make this work perfect. That is, the areas where rainwater or the like may enter from the outside are the area between the periphery of the pillar through hole 9 in the center of the synthetic resin waterproof cover 10 and the pillar 1, and the area between the lower surface of the periphery of the waterproof cover 10 and the waterproof sheet 4. There are two places between
Rainwater, etc. from the former is sealed by the welded part 14 between the contact surfaces with the mounting board 2, and is further filtered through the screw hole 7 between the lower end of the column 1 and the mounting board 2 to the waterproof sheet 4. Even if it reaches the top, the water is sealed by the welded portion 12 between the mounting board 2 and the waterproof sheet 4, and does not reach the penetrating portion of the fixing screw 6. Needless to say, rainwater from the latter is prevented from entering the inside by the welded part 15 between the hakama part 10a of the synthetic resin waterproof cover 10 and the waterproof sheet 4. Therefore, the infiltration of rainwater and the like into the subfloor 5, which causes water leakage, is completely prevented, and a high waterproofing effect can be achieved.

Moreover, each of the welded parts 1 that performs the water sealing function
2, 14, and 15 are all joined by means of welding between the resin contact surfaces using a solvent-based adhesive, etc., so there is no risk of deterioration over time, and the above waterproof function can be maintained for a long time. It has the effect of being able to be held securely across the body and improving durability.
